United States Patent 3,437,214 SHELVES John Sainsbury, Little Aston, England, assignor to Sainsbury & Parkinson Limited, Wallsall, Stalfordshire, England, a corporation of Great Britain Filed Aug. 1, 1967, Ser. No. 657,589 Claims priority, application Great Britain, Aug. 6, 1966, 35,311/ 66 Int. Cl. A47f /08; A471) 47/00; E04g 3/04 US. Cl. 211-90 17 Claims ABSTRACT OF THE DISCLOSURE A shelf assembly comprises a mounting strip, a shelf arranged to be supported along one edge in a longitudinal channel in the mounting strip and a pair of end caps. The end caps are arranged to fit over the ends of the mounting strip and shelf to maintain these two members in assembled relationship. The shelf assembly is suitable for mounting on a wall above a central heating radiator and includes means for providing a draught-proof seal between the mounting strip and the wall.

This invention has reference to shelves and has, as its principal object the provision of a shelf assembly which is economical to manufacture, is capable of being mounted in position quickly and easily and, when so mounted, is neat and attractive in appearance.

According to the invention a shelf assembly comprises a mounting strip defining a longitudinal channel of which one side is deeper than the other, a longitudinal lip on the mounting strip at each side of the channel extending inwardly of the channel mouth, a shelf engageable in the channel to be co-extensive therewith with opposite sides of the shelf in abutment with the lips, and two recessed caps each engageable over one end of the mounting strip and the shelf when mounted therein and operative to prevent disengagement of the shelf and mounting strip.

Preferably, the mounting strip or at least those parts thereof defining the sides of the channel is or are capable of limited resilient deflection, and the perpendicular distance between the free longitudinal edges of the lips, that is the spacing between these edges transversely of the channel, is less than the thickness of the shelf. Consequently when inserted in the mounting strip channel the shelf extends at a slight inclination to the perpendicular to the base of the mounting strip and must be forced into the perpendicular before it is possible, to fit the end caps in position. This causes the sides of the channel to be forced apart and resiliently stressed, so that when the end caps are fitted this stressing produces an improved engagement between the end caps and shelf and mounting strip.

Preferably, each longitudinal edge of the shelf is provided with ribs which project beyond the opposed lipabutting shelf faces and the thickness of the ribs is less than the distance between the mounting strip base and lip or the shallower side of the channel, so that after engagement of one edge of the shelf in the channel and before fitting of the end caps a limited movement of the shelf towards and away from the base is possible. Hence when, as intended, the mounting strip is secured horizontally against an upright surface of a wall or like rigid support, the engagement of the ribbed shelf edge in the channel is not hindered should the strip be distorted as a consequence of any uneveness of the said surface.

Preferably, the end caps comprise metal die-castings formed with grooves to receive the ends of the shelf and mounting strip, and having one or more lugs or studs to assist location of the end caps.

The mounting strip can be of any suitable construction but preferably comprises a steel pressing of generally triangular shape in section and having a flat base for mounting against the supporting surface. The base of the mounting strip can be provided with a longitudinal groove to receive a strip of felt, rubber or other sealing materials so that when the shelf is mounted no air currents can pass between the mounting strip and the supporting surface. This feature is particularly desirable where the shelf is to be mounted on a wall above a central heating radiator, since the sealing strip prevents staining of the wall above the shelf commonly caused by air currents convected behind the rear edge of a shelf.

The invention will further be described, by Way of example only, with reference to the embodiments illustrated in the accompanying drawings, in which:

FIGURE 1 is a perspective view of a shelf assembly according to the invention;

FIGURE 2 is an exploded perspective view showing details of the components of the assembly;

FIGURE 3 is a cross-sectional view showing the shelf assembly mounted on a supporting wall;

FIGURE 4 is an exploded perspective view showing details of two components of an alternative form of shelf assembly in accordance with the invention;

FIGURE 5 is a cross-sectional view showing one stage in the mounting of the shelf assembly of FIGURE 4; and

FIGURE 6 is a cross-sectional view of the shelf assembly of FIGURES 4 and 5 mounted on a supporting wall.

Referring first to FIGURES 1 to 3 the shelf assembly shown comprises a mounting strip 10, a shelf 11 and two end caps 12. The mounting strip 10 is fabricated in wood and is triangular-shaped in cross-section having a fiat base 14 and a longitudinal channel 15 defined by two limbs 16 and 17. The limbs 16 and 17 carry longitudinal lips 18, 19 respectively extending inwards of the channel mouth, the limb 16 being shorter than the limb 17. The mounting strip is provided with a plurality of holes 20 extending through the base and the mounting strip can be secured to a supporting surface as by screws passed through these holes.

The shelf 11 is suitably fabricated in chipboard and covered on opposite sides with veneers of different colours and/or patterns. The longitudinal edges of the shelf carry -shaped members 22 secured thereto and providing longitudinal ribs 23 which project beyond the opposite surfaces of the shelf. The shelf is of a thickness equal to the perpendicular spacing between the lips 18, 19, the thickness of the ribs being less than the distance between the lip 18 and the base of the channel in the strip 10.

Each end cap 12 comprises a moulding in thermosetting synthetic plastics material and contains a recess 24 corresponding in shape to the assembled profile of the shelf and mounting strip. Within the recess 24 is carried a wedge-shaped lug 25 which in the assembled condition extends into the channel 15 between the limb 17 and the underside of the shelf 11 and between the lip 19 and the rib 23, making a friction fit between the shelf and the strip 10. If desired the portion of the recess 24 which registers with the shelf end may be of greater deph than the portion of the recess which registers with the mounting strip end so that should any part of the shelf end extend beyond the strip end, assembly of the cap is not hindered.

An alternative and preferred form of shelf assembly is shown in FIGURES 4 to 6 and comprises a mounting strip 10a, shelf 11 and end caps 12a. The mounting strip comprises a channel section metal pressing formed with folded over lips 18a, 19a, and defining a channel to receive the shelf 11. The perpendicular distance between the lips 18a, 19a is less than the thickness of the shelf 11, so that when the shelf is inserted in the channel it is inclined out of the perpendicular to the base of the strip as indicated in FIGURE 5. The shelf must be forced into the. perpendicular before it is possible to fit the end caps 12a, and in the assembled condition shown in FIGURE -6 the limbs of the strip 101: are, therefore, flexed apart and resiliently loaded, thus producing reactive forces between the shelf and the end caps which positively prevent relative movement between the shelf and the strip. Each cap 120 comprises a Zinc die casting and, includes two spaced tapered studs 26 which are arranged to engage the mounting strip 10a at opposite ends of the base thereof as indicated in FIGURE 6 The studs 26 are spaced from the wall of the recess 24a of the end cap by a distance equal to the thickness of the metal of the mounting strip. In the assembled condition studs 26 resist any tendency for the end caps 12a to be tilted by the reactive forces applied to the shelf by the limbs of the mounting strip 10a.

A longitudinal groove 27 in the base 14a of the strip 10a received a strip 28 of sealing material such as felt. In its free condition the strip 28 is of greater thickness than the depth of the groove 27 so that when the strip 100 is mounted on a wall the strip 27 is compressed and effects a draught-proof seal between the mounting strip and the wall.

One of the primary purposes for which the assemblies described are intended is to provide a shelf above a radiator of a central heating system. The mounting strip and shelf can be manufactured in standard length and cut on site to a smaller length determined by the length of a radiator.
